# generate ca and tls certs for elasticsearch cluster
|
|
|
|
start a `bash` in an elasticsearch image, such as `docker.elastic.co/elasticsearch/elasticsearch:7.17.0`: `docker run -ti docker.elastic.co/elasticsearch/elasticsearch:7.17.0 bash`

generate a ca and node certs:
|

|
./bin/elasticsearch-certutil ca
|
|
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
|
|
```
|
|
|
|
copy `elastic-certificates.p12` to `/mnt/ssd/telemetry/es_data` in all nodes, and chown it:
|
|
|
|
```bash
|
|
chown 1000 /mnt/ssd/telemetry/es_data/elastic-certificates.p12

# create elasticsearch passwords
|
|
|
|
in elasticsearch container
|
|
|

|
./bin/elasticsearch-setup-passwords auto
|
|
```
|
|
|
|
save passwords in consul, at:
|
|
|
|
- `secrets/telemetry/elastic_passwords/apm_system` for user `apm_system`
|
|
- `secrets/telemetry/elastic_passwords/kibana_system` for user `kibana_system`
|
|
- `secrets/telemetry/elastic_passwords/elastic` for user `elastic`
|

|
|
- on index `apm-*` privileges `create_doc`, `create_index`, `view_index_metadata`
|
|
- on index `apm-*sourcemap` privilege `read_cross_cluster`
|
|
|
|
create user `apm` with roles `apm_writer` and `apm_system`. give it a randomly generated password that you save in `secrets/telemetry/elastic_passwords/apm`
|
